1st :The angle of depression 30° = the angle of elevation (from the truck to the height of the building.
2nd :
cos 30° = (adjacent side)/(hypotenuse)
cos 30° = x/100, but cos 30°= (√3)/2
(√3)/2 = x/100 and x = (100√3)/2
and x = (50.√3) = 86.60 m
draw the lines down all the ways that it is equal on each side
Answer:
x= -0.2 or -1/5
Step-by-step explanation:
42+5X=41
Subtract 42 from both sides:
42+5X=41
-42 -42
You are left with:
5x=-1
Now divide 5 by both sides to isolate x:
5x= -1

5 5
x=-0.2 or -1/5
